Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487850, here are decompositions:

7 + 487843 = 487850
19 + 487831 = 487850
31 + 487819 = 487850
61 + 487789 = 487850
67 + 487783 = 487850
109 + 487741 = 487850
193 + 487657 = 487850
199 + 487651 = 487850

Showing the first eight; more decompositions exist.
